Slice the tomatoes to the same width as the courgettes and place in a colander or sieve set over a bowl. Sprinkle with leaves from 2 of the oregano sprigs, a pinch of flaky sea salt and the sherry vinegar. This will marinate the tomatoes, and the juices collected underneath make a tasty dressing for the rocket garnish. Leave the tomatoes to marinate for 5 minutes, then pat dry with kitchen roll before they start to go soggy
